The Details on Detailing
This is a multifactored and design-dependent catch-all term. It includes stitching time, quantity of small pieces and layers, and methods used.
Because each custom collar is entirely unique and designs so subjective, I cannot appropriately determine the cost of effort and time in designing/stitching/finishing a collar. Some collars feature things others don’t. That is the nature of a custom designed collar, additional fees are subject to each individual design.
